The fair use concept embedded in US copyright law maintains that certain uses of copyright-protected works do not require permission from the copyright holder. If you have a specific question that is not answered on this website please complete and submit our Copyright Request Help form.
Four factors must be considered when determining if your purpose is fair use: (1) Purpose and Character of the Work, (2) Nature of the Work, (3) Amount Used, and (4) Effect on the Market.
